Topic: Mining btc from a usb stick? (Read 156 times)

Two things:

1) No you don't go buying USB miners to make a profitable mining company - everyone knows that - no one does that.
You buy USB miners for learning about bitcoin mining, for fun and for lottery mining since they use so little power.
As I already stated above, the rewards on those old slow small USB miner is 100's of times smaller than a current miner.

2) The current USB miners are around 365GH/s at around 15W
i.e. 3 of them, with simple cooling, can get you 1.1TH for around 45W

Do not even think about buying these USB sticks. USB miners are no longer profitable, USB bitcoin mining has died down in profitability due to multiple factors. USB miners made it easy for you to get started with bitcoin mining, however, due to increasing adoption, bitcoin halving, and other factors, the profitability has died.

Sapphire Block Erupters were the first-ever miners to be created. Releasing the power of 330Mh/s of hash power, the user would be able to receive nothing less than $0.01/month thus not enough to earn profitability.

Relation to the ASIC bitcoin miner USB, it generates a power of 25 gigahash/second which is, nowadays; almost nothing but not that much due to the rise in the difficulty of obtaining Bitcoins. The device will need active cooling as it gets hot due to the processing i.e 80 degrees on the heatsink. So how does it work?

Firstly, you insert the device into the computer, download the drivers, download the mining software which is the CG miner.
Inform the software with a batch file on the BTC address, where it should send the payment to and to perform either a solo or pool mining and setting the frequency in which you can run it depending on the frequency you get more hash rate with higher power consumption or less hash rate with low power consumption.
You will be then ready to mine.

Anyways, Don't waste your money. Buy Crypto and hold them. Good Luck

No, they will probably make no money. Then again these are aka "Lottery Sticks" because there IS a chance you might get a block from a solo pool. In that case -- cha ching!! If you sometimes buy a lottery ticket then ya might as well go for a stick to try your Luck because at least they are dirt cheap to run.

  You will make 0$ so if you wish to waste money go ahead with these usb sticks

I haven't watched the complete video... just the first 10 seconds...
This guy is showing a newpac usb miner... You can find them on sites like this one: https://www.bitshopper.de/en/shop/sha-256-miner/usb-miner-bitcoin/newpac/

The device hashes @45Gh/s (maximum... it is rather difficulty to make those usb miners run consistently at those speeds), and at these speeds it'll draw close to 10 Watts.
Let's assume for a moment, you're able to get it running @45 Gh/s whilst it draws 7 Watts and disregard the power consumption of the rPi (or pc) you need to connect it to. Let's also assume you only pay 5 cents/Kwh for your power.... These are huge assumptions: you'll probably won't keep it running @45Gh/s consistently, if you do it won't consume only 7 Watts, and you'll probably pay way more than 5 cents/kwh

Let's plug in those numbers at a mining calculator:
https://www.coinwarz.com/mining/bitcoin/calculator?h=45.00&p=7&pc=0.05&pf=0.00&d=19893045048575.00000000&r=6.25000000&er=1&btcer=59348.38830000&ha=GH&hc=11999.99&hs=-1&hq=1
Even at these absurdly low assumptions, you'll only make 1 cent/day, so it'll take you 12.000 to recuperate your initial investment (not including the S&H, taxes and customs charges... Nor the investment of an rPi).

Even if you disregarded electricity completely, this gear would still only make 2 cents/day...

so it would be possible almost i'm tempted, of course the gains would be much lower but also the energy consumption would be almost zero, is a fairly recent video of 2021 without wanting to advertise them i place the link in case tell me and i will removed it https://www.youtube.com/watch?v=FyRGkbu-LB8

What year was that video you're talking about posted?
I have a couple of those sticks laying around... I stopped using them many, many years ago...

It would be an ASIC USB stick like this one:
https://bitcointalksearch.org/topic/gekkoscience-has-a-new-stickminer-that-does-300gh-5355470

Of course it's 200-300 times slower than a 100TH/s miner so makes 200-300 times less ...

All older ones would be slower than that one also.

hello i saw a video on you tube of someone who mined btc (even with a certain profit) with usb sticks connected to a notebook, of course the energy savings would be considerable, the demand is it is really possible to mine in this way instead of with an asic?
